    2021 wholesale price Low Cement Castable - Low Cement Castable – Topower

    Description Low cement castable refers to a castable with a lower amount of cement. The cement dosage of refractory cement castables is generally 15% to 20%, and the cement dosage of low cement castables is about 5%, and some even reduce to 1% to 2%. The purpose of reducing the amount of cement is to improve the fire resistance of the castable. Low-cement castable is a high-tech refractory developed on common castables by using rheological principles, the tightest packing theory and ultra-fin...
